Readable mixed Arabic/English and Hebrew/English paragraphs #1939

User outcome

Choose paragraph direction from meaningful text while keeping code and file paths left-to-right. Cover mixed text, punctuation, links and lists with visual cases.

Current scope

Markdown paragraphs currently render without paragraph-level direction handling. This is source evidence of a gap; a live Arabic/Hebrew UI test was not performed.

Acceptance criteria

• Choose paragraph direction for mixed Arabic/Hebrew and English content.
• Keep code, file paths and technical blocks readable left-to-right.
• Verify punctuation, lists, links and first-strong direction with representative visual fixtures.

Verification

Add focused behavior coverage for the changed path, run relevant checks and record any unverified platform/provider behavior. Do not alter real user credentials or settings during tests.
